This morning I was informed of a Snowy Owl perched atop one of our hangers. Around 7:30 am we went out and had a little looksie and sure enough an almost completely white Owl was sitting atop a metal roof access ladder at the East end of the Hanger.
Talking to one of our Flight mechanics afterward, apparently a group of them spotted a similar Owl last week as they were taxiing an aircraft back to the ramp parking area.

p.s. Spotted Coopers Hawk around our house twice in the last couple of days. Today sighting was just up the street, it flew off as I approached the tree along the sidewalk it looked out of control but it was the strong winds that caused it to fly in drunken like manner.
